Area and Volume Errors in Reservoir Projects
In reservoir planning-design, the engineer is facing the task of determining area of tracks of land, of surfaces covered by the reservoir water, and of the volumes of water contained in...

Volume Changes in Sands during Cyclic Loading
Measurements of the volume change behavior of sands under cyclic loading simple shear conditions suggest that the vertical strain due to compaction depends only on the shear strain amplitude...

Traffic Volume Characteristics on Urban Freeways
Various traffic characteristics for urban freeways are derived from data recorded at 15 urban locations in 1965 and 19 urban locations in 1963. This study was directed toward developing...

Comparison of Stress-Dilatancy Theories
The stress-dilatancy theories of Rowe (1962) and of Newland and Allely (1957) are considered. A more precise derivation of Newland and Allely's volume change equation is given and subsequently...

Service Volumes for Functional Classification
Highway agencies adopting or exploring functional classification will find advantages in using the level of service concept of the 1965 Highway Capacity Manual in establishing service...

Concrete Volume Change for Dworshak Dam
Measures required to control volume change and prevent detrimental cracking in mass concrete were determined by test and analysis. This straight gravity dam 717 ft high with a base width...

Surge Problems in Canals with High-Lift Locks
Investigations for new navigation canals and rehabilitation of existing canals are leading to larger lock sizes and higher lifts. In order to maintain a high traffic capacity and a short...

Volume Change Characteristics of Unsaturated Clay
Compression tests under controlled effective stress paths show the stress path independence of volumetric strain and degree of saturation. Stress path dependency appears to be caused by...

The Significance of Cap and Base Restraint
Techniques for reducing cap and base restraint are discussed, and a method for assuring effective elimination of restraint with lubricated caps and bases is presented. The effects of cap...

Nominal Diameter of Floc Related to Oxygen Transfer
Nominal diameters of activated sludge floc have been determined on samples obtained from eight activated sludge plants. These plants ranged in size from a large conventional plant to a...

Ground Control of Airport Traffic
As a result of complex airport geometry and high traffic volume, the control of aircraft on the ground is becoming increasingly difficult. Poor weather and night add to the problems. Airport...

Predicting The Modal Split In Pittsburgh
During the preparation of a regional transportation for 1980, the Pittsburgh Area Transportation Study was required to predict future tripmaking as distributed between the automobile and...

Capacity Of Urban Transportation Models
Information on capacity of various modes of urban transportation is an essential tool in urban transportation planning. Based on the capacity of urban freeways and arterials to carry vehicles...

Terminal Building Area Planning: Parking and Circulations of Vehicular Traffic at Airports (Increasing Airport Capacity An ASCE-AOC Joint Conference 1961)
Results of studies on vehicular traffic at San Francisco Int Airport; use of average peak hour traffic volume as design hour for parking requirements; existing and planned parking facilities...

Pore Pressure and Volumetric Measurements in Triaxial Compression Tests

Inventory of Highway Needs
The Federal-Aid Highway Act of 1958 required each state to prepare cost estimates of the needs of the various road systems within the state. This paper outlines the procedures employed...

Pavement Design Practices in Virginia
Virginia uses modified CBR method for designing highway pavements; primary and Interstate Systems are divided into 6 classes on weight and volume of truck traffic; design wheel loads vary...

Characteristics of Traffic Flow on Freeways
Traffic flow characteristics were studied on two high density controlled access facilities in Detroit, Mich; average speeds and volumes were recorded on per minute, per lane basis; paper...

Operation of Urban Expressways
Reasons for stoppage when caused by too great traffic density is explained; procedure for analyzing traffic is suggested; it is proposed that traffic entering expressways be controlled...
